This master's thesis, "S in ESG: Assessment of Social Sustainability in Real Estate," authored by Marianne Sar, investigates the identification and evaluation of social sustainability within real estate, particularly commercial properties. It critiques the EU Social Taxonomy proposal, which highlights three stakeholder groups—employees, consumers, and communities—and aims to promote decent work and inclusive communities. The analysis of the ÖGNI certification system reveals that only 22 out of 45 criteria are relevant for assessing social sustainability, indicating significant gaps. The research identifies the need for 15 additional criteria to align with Social Taxonomy standards and recommends integrating insights from other frameworks like GRESB. Ultimately, the thesis underscores the necessity for standardized metrics to evaluate social impact within the real estate sector, contributing to the broader discourse on social sustainability.
This master's thesis titled "S in ESG: Assessment of Social Sustainability in Real Estate - Critical Analysis of Social Taxonomy and Limitations of Certification Systems" was written by Marianne Sar and submitted in February 2024 at a university in Vienna, Austria.
Context and Purpose
The thesis examines how social sustainability can be identified, measured and evaluated in real estate, with a particular focus on commercial properties. It analyzes the growing importance of social aspects within ESG frameworks while highlighting the current emphasis on environmental factors in the real estate sector.
Key Findings
Social Taxonomy Framework
- The EU Social Taxonomy proposal identifies three main stakeholder groups: employees, users/consumers, and communities/society
- It establishes three primary objectives: promoting decent work, ensuring adequate living standards and wellbeing, and fostering inclusive communities
- The framework differs from environmental taxonomy as it relies more on conventional standards rather than scientific metrics
Certification Systems Analysis
- The study focuses on the ÖGNI (Austrian Sustainable Building Council) certification system
- Out of 45 total ÖGNI criteria, only 22 were found relevant for social sustainability assessment
- The system covers only 59% of the Social Taxonomy's 37 sub-objectives, revealing significant gaps
- Socio-cultural quality criteria showed 100% alignment while economic quality criteria showed zero alignment
Limitations and Recommendations
- Current certification systems lack comprehensive coverage of social aspects
- 15 additional criteria need to be developed to fully align with Social Taxonomy requirements
- The thesis proposes integrating perspectives from other frameworks like GRESB and ICG model
- Suggests more flexible assessment approaches to account for different contexts and situations
Significance
The research provides one of the first comprehensive analyses of how real estate certification systems align with the proposed EU Social Taxonomy. It identifies specific gaps and proposes concrete ways to enhance social sustainability assessment in the real estate sector, particularly for commercial properties.
The thesis contributes to the emerging discussion on social sustainability metrics in real estate while highlighting the need for more standardized approaches to measuring and evaluating social impact in the built environment.
